“…2). Significant morphological and developmental differentiation depending on the genotype was reported by other authors as well [Cromack andSmith 1998, Gesch 2013]. The morphological traits of the pot marigold exhibited changes induced by the humidity and thermal conditions.…”

Influence of nitrogen fertilization on the seed yield and the content and quality of fat in pot marigold (Calendula officinalis L.) cultivarsWpływ nawożenia azotem na plon nasion oraz zawartość i jakość tłuszczu wybranych odmian nagietka lekarskiego (Calendula officinalis L.)Summary. Pot marigold seeds contain oil with a specific composition (presence of calendic acid); hence, they can be used as an alternative oil raw material. In 2011-2013, a field experiment was conducted to determine the effect of different nitrogen doses (0, 30, 60, 90, 120, 150 kg N·ha -1 ) on the seed yield, oil content, and fatty acid composition in four pot marigold cultivars. Nitrogen fertilization exerted a positive effect on the number of flower heads and seed yield. However, the response of marigold cultivars to nitrogen doses applied varied, i.e. the yield of the 'Tokaj' and 'Radio' cultivars was significantly increased up to the dose of 60 kg N·ha -1 , whereas such an increase was noted in the 'Orange King' and 'Persimmon Beauty' cultivars at the dose of 90 kg N·ha -1 . Nitrogen fertilization modified the content of fat: the low nitrogen doses (30 kg N·ha -1 ) did not influence the fat content in the seeds, whereas the increasing doses resulted in its gradual decline. The cultivars were characterised by significant differences in plant morphology, seed yield, and fat quality. During the three-year period, the highest seed and fat yields were determined for the 'Orange King' cultivar (1857.3 and 399.3 kg·ha -1 , respectively) and the highest proportion of calendic acid in the oil (54.86%) was detected in the 'Persimmon Beauty' cultivar. The yield and quality of marigold oil depended on both nitrogen fertilization and the weather conditions prevailing during the growing seasons. The increase in the nitrogen doses was accompanied by an increase in the content of linoleic acid and a decrease in the level of oleic acid. The cooler and wetter growing season in 2011 turned out to promote the highest fat and calendic acid accumulation.

“…These results are in conformity with those of Jan et al (2000) Fruit yield (number and ton/fad.) decreased in low plant population probably due to the environmental factors including light, space, water and soil which are not optimally used (Cormark and Smith, 1998;Rassam et al, 2007) and the decrease in number of fruit per area at low population could be attributed to reduction in number of plants per hectare and this consequently, reduce the number of fruitful branches (Knavel, 1988;Walters and Schultheis, 2000). These results are in a good line with those reported by Shukla and Prabhakar (1987) on bottle gourd, Maynard and Scott, 1998 on muskmelon, Jan et al (2000) on bottle gourd, Kultur et al (2001), Goreta et al (2005), Ban et al (2006), Ban et al (2011) on watermelon, who reported that total yield and numbers of fruit per hectare were linearly increased with the increase in plant population.…”

This experiment was carried out during two successive summer seasons of 2012 and 2013 on bottle gourd landrace El-Arishy (Lagenaria siceraria M) at the Experimental Research Farm of the Faculty of Agriculture, Suez Canal University, Ismailia, Egypt to study the effect of plant density and nitrogen fertilizer on plant growth, yield and its components as well as mineral content. The obtained results showed that the low plant population (1750 plant per fad.) gave the highest shoot fresh weight, shoot dry weight, average fruit weight, average fruit length and nitrogen content in shoots and fruits. However, the significant highest fruit yield and fruit number per faddan were associated with the high plant population (3500 plant per faddan). All previous mentioned parameters in addition to shoot and fruit phosphorus contents significantly improved by application of high nitrogen rate (20g/plant). Shoot and fruit potassium and phosphorus contents were not affected significantly by plant spacing. Fruit potassium content did not affect significantly by nitrogen fertilizer. All the above mentioned parameters were significantly higher with the interaction between low plant population (1750 plant per fad.) was combined with high nitrogen rate (20g/plant), except fruit yield (ton/fad.) and fruit number which increased by the combination of high plant population with high nitrogen rate. Potassium content did not affect by the interaction between plant spacing and nitrogen fertilizer.

“…It can be locally applied to inflammatory changes in the lining of the mouth and throat wound. Cromack lists four different possibilities of using calendula: as medicinal plants, in the cosmetic industry and in the production of natural colors [9]. Russians used it for the manufacture of compositions that are used in the symptomatic treatment of some forms of cancer, and its anti-HIV properties are recently revealed [10].…”
